Deskripsi

Abstract We present for the first time resummed predictions at NLO + NLL′ accuracy for the Durham jet-resolution scales y n,n+1 in multijet production in e + e − collisions. Results are obtained using an implementation of the well known Caesar formalism within the Sherpa framework. For the 4-, 5- and 6-jet resolutions we discuss in particular the impact of subleading colour contributions and compare to matrix-element plus parton-shower predictions from Sherpa and Vincia.
